|Braies (or Breeches) were the innermost layer of mens clothing. They fill in the gap between single leg hose in the 13th and 14th centuries. As hose became fuller, braies got smaller.
There are no surviving examples of braies as linen rots away too quickly. All these examples are “best guesses” worked out from pictorial evidence.
Long leg braies were worn between single leg hose. “Boxer” braies are an alternative pattern for the same garment, with less fullness in the rear.
15th century braies are worn under joined hose, the Italian braies are seen in paintings from the end of the 15th century.
